The video is nearly seven minutes long but The Telegraph has decided to show only the first two minutes.

Rodger is believed to have shot his victims as he drove a black BMW around the area of Santa Barbara where the University of California is situated.

He got into two gun battles with police before crashing into a parked car. Police found him dead with a gunshot wound to the head. It is not clear if the wound was self-inflicted or the result of a shoot-out with police.
